I have one customer's carbon frame in the warranty pipeline right now with two cracks in his top tube (which the company was not going to cover under warranty) and a fortuitous crack in his chainstay which they *might* cover after getting a firsthand look at it. Anyway, it's up to you but the safe money is on supporting it by the wheels, particularly if it's high-end thin-walled carbon.

Not to threadjack, but we have a Thelma2, which is one of the ones that uses wheel support. We took our bikes on a couple of hour road trip and the winds got quite high (gusts may have hit 40mph and we were at Interstate speeds). I had the straps tight and the rack as tight as I could get it, but the bikes still moved quite a lot. My wife was concerned that the movement could cause damage to the fork or stays (I think she was thinking of the movement causing torque etc.)

I told her I didn't think that was an issue, but who would be right? She's really sensitive about her bike right now.

I remember cringing when I went over a couple of speedbumps and saw both my wife and my carbon top tubes bouncing up and down off the bike rack supports. Just didn't feel right...and I think her 'owner's manual' specifically cautioned against it.

If you check the owner's manual, I think it says you're supposed to let your wife ride inside the car...
